OK guys, need some help.
My dad has been getting cramps at night if he does a bunch of physical work the day before. I kept telling him it was dehydration as he drinks a bunch of coffee in the mornings. So he got a minor stomach bug over the weekend and didn't eat or drink much. He then said he didn't have any cramps when he didn't drink as much.
I told him to go to the doctor, which he won't do. I know it isn't much good information to go on, but I'm trying to figure out what the deal is. I don't want him just drinking less water because he thinks it causes cramps. I'm thinking it is some electrolyte imbalance or something. Anybody have any idea what's going on?
